7.30 can reveal that Radiance International Inc received the $2.5 million contract from the Australian Department of Home Affairs for refugee accommodation structures on Nauru.

Tender documents show the contract was dated between December 2016 and July 2018, and is described as "refugee accommodation-Budapest Hotel, Nauru".

According to Mr Bhojani's website, Radiance International has provided "medium term" housing in Nauru "to accommodate both the growing number of foreign workers on the island and the number of refugees seeking to settle temporarily in Nauru".

"The department can confirm it has accommodation lease arrangements on Nauru with Radiance International," a spokeswoman from the Department of Home Affairs told 7.30.

"As this is a matter that is before the courts, it is inappropriate to comment further."
